The good news is that the bird pets will ping them as a rare. There are no panthers here so if you see a red asterisk with your bird out it is probably one of these guys. I have never seen one during the day, last night using this map I found two of them about 20 minutes before night cycle on the first one and the second one after ten game time. They do not respawn quickly or if they do they are not respawning in the same place I hung around one spot for an hour he didn't come back again. Killed two did not get the knowledge so this is another one that's a pain to obtain keep out your birds eat your dreighan meals or the cron that has knowledge boost looney pots put it all out there! They are on the edge of the cliff they do not spawn farther in where all the other fadus mobs spawn can't miss em, bigger and have the winged costumes like the holy men. Be ready to kite they have a lovely rush attack.

Just server hopped a few times. There seems to be only 2 of them alive at a time.
